I-IIGH-ARGH-REPAIR LAST. Y

Specification of Letters Patent. Patented Ap1g19, 1921,

Application filed July 8, 1920. Serial No. 394,640.

T 0 all whom. it may concern Be it known that I, GEORGE DOERING, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a new and useful High-Arch-Repair Last; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to repair lasts and has for its object to provide a last for repairing high arched womens shoes, said last comprising an elongated tapered body portion adapted to engage within the shoe, the rear end of the elongated body member terminating in a downwardly and outwardly curved surface adapted to engage the concaved portion of the forward convolution of the shoe arch, with which the rearwardly and downwardly extending portion of'the I body member engages and to provide means whereby the last may be supported by a jack carried extension sleeve, which sleeve is provided with means whereby the shank of the last and the jack will be prevented from jamming and spreading in said sleeve.

A further object is to provide the lower end of the vertical portion of the last with a reduced portion, which reduced, portion is adapted to be received in a socket of an extension attachment, which attachment is also provided with a socket adapted to receive the upper end of a conventional form of repair jack, thereby allowing the workman to stand up or sit down while repairing shoes.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of the last showing the same supported on a conventional form of repair jack and the extension attachment in use, also showing a conventional form of high arch shoe on the last. 7

Fig. 2 is a perspective view of the last.

Fig. 3 is a horizontal sectional view taken on line 3-3 of Fig. 1.

Referring to the drawings, the numeral 1 designates a portion of a conventional form of repainjack, which jack may be supported on any form of base and secured to any form of support. The upper end of the repair jack is provided with a rectangularly shaped portion 2, on which rectangular portion the extension attachment 3 is placed, by placing the rectangularly shaped portion 2 in the socket 4:. The bottom of the socket 4 is preferably inclined as at 5, against which incline the inclined end 6 of the rectangular portion 2 engages. By providing the inclined engaging surfaces, it will be seen that the spreading and consequent binding of the rectangularly shaped portion 2 will be obviated.

Extension attachment 3 at its upper end is provided with a socket 7 for the reception of a reduced portion 8 of the shank 9 of the last 10. Reduced portion 8 has its lower end 11 angularly disposed so that it will not spread when forced into engage ment with the angularly disposed bottom 12 of the socket 7 The reduced portion 8 is provided with flat portions 13 and concaved portions 14 adapted to engage similarly shaped surfaces in the socket 7 so as to counteract the tendency to wabble during a half soling operation, incident to nailing.

The last 10 comprises the bodv portion 15, which portion conforms to the shape of the interior of the shoe forwardly of the shoe arch 16 and is provided with a flat surface 17, which engages the interior wall of the shoe sole. Flat surface 17 at its rear end merges into a rearwardly and downwardly extending curved surface 18, which curved surface engages the concaved surface 19'0f the forward convolution 20 of the high shoe arch 16. i

It will be seen that during a half soling operation that the last will snugly fit the concaved surface 19 of the forward bend 20 of the shoe archand thatthe last will not come in engagement with the rear bend 21 which is the objection to the last now in use. Where the last engages the bend 21 it has been found that the shoe arch is the arch, wrinkles develop in the shank of the upper adjacent the arch, thereby not only injuring the shoe, but also causing the shoe to be out of shape and to present an objectionable appearance.

The invention having been set forth what is claimed as new and useful is The combination with a repair jack having a rectangular shaped head and a reduced portion of a shoe last, of an extension member therefor, said extension member comprising an elongated member, provided with sockets at its ends, the bottoms of which are disposed at an incline to the side walls of the sockets for the reception of the rectangular head of the repair jack and the reduced portion of the shoe last, said rectangularhead of the repair jack and the reduced portion of the shoe last having inclined end surfaces for engaging the bottoms of the recesses in the extension member.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
